y ANTICBEEPER.

To allwhom t may concer/n.' p l V Beit known that I, HoRA'rIo G. GILLMOR, of -Washington, in the District of Columbia, have invented a newl and usefull Improvement in Anticreepers, of which the following is a specification, accompanied by drawlngs.

This invention reiates to devices known as rail anticreepers, rail anchors or rail stays and one l'of its objects is to form a I simple device which will prevent longitudina'l movement of the rails of railways.

l Other Objects ofthe invention are to provide means for securing the device upon the rails yin such manner that it cannot be looscned-b vibration or reverse movement of the' ra' and to provide a device which shall be effective against movements in either direction.

Tothe accomplishment of these objects andsuch others as may hereinafter appear, asg'w-ill be readily understood by those skilled in the art, the .invention comprises an anticre'per, embodying the features of construction, thegcombination of elements and arrangement of parts having the general mode ofioperation as hereinafter described and claimed.

Beyond .the shoulders C and D the bar is turned back in the form of partial loops F and Gr andthe ends ofthe bar arev each formed with. aws H and I arranged to engage the lbase ange of t rail at opiosite sides of the Vwiththe rms K `an L above and Speoicationpf Letters Patent. .Patented Application led April 14, 1915.

the broad flat portions kM and N below rail base. and Oare two ties.

The device isplaced in position on the rail by'l placing the body B transverse and inclined to the rail Awith the base ange at one sideentered in the jaw H and the shoulder E and the arm L oi the other end of l clearing the other edge of the rail base as illustrated `in Fig. 3. The whole isthen moved angularly in relation to the rail and at the same time the end having the jaw is sprung upwardly so that the jaw I will engage the rail base at the side of the rail. The parts are then in the position illuslthe tratedv in Fig. 4 and the body B is under i opposite edges of the rail base are engaged A bythe shoulders D and E.

The grip of the jaws H and I upon the rail insures that the device will move with the rail until one or the otherot the' portions M or N come into Contact with the l tie. In the drawings it is assumed that the rail normally tends to move in the direction of the arrow in Fig. 1 and this direction will be referred to as forward. After 'the rail moving :forwardly has brou'ghtfft into engagernei-it with the 'tie 0,' the contactl of M with the tie Owiifi prevent further movement of M forwardlj, and, if the grip of the device on the rail is not then sufficient toi-hold the rail against the forces operating to cause it to move forwardly, further movevment of the rail in the forward direction will carry the j aw I'and the shoulder E forward with the rail and will cause the body B to assume a new position at an angle to its first position. y'lhe-efl'ect of this-will be to increase the pressure of the shoulders D grip of the device upon the rail until the grip of the device becomes sufiicient to liold land E upon the rail edges and tighten the the rail against lfurther movement in this direction.

Should the rail A, on account of change in temperature or for any other reason move in' the reverse or backward direction, it willf carry with it the device B and .the portion M will be carried out ofcontact'withthe rail if this movement continues. Should this occur, the engagement of the jaws H and I with the rail bases and the torsion of B will prevent vibration from loosening or disengaging the device from the rail. Moreover, should this rearward or backward the rail would he held against movement .b in either direction except for such small movement as might be necessary 'to bring aboutsuch tightening of the grip of the device in passing from movement in one direction to movement in' the other direction. Obviously some features of the invention may be ,used Iwithout others and the invention may= be' embodied in widely varying forms within the scope of the artisan.

Therefore, without limiting the invention to the construction shown and described or enumerating equivalents,l I claim anddesire to secure by Letters Patenti- 1. A rail stay, comprising a cross bar recessed to receive'tlieA rail base flange and engage the opposite vertical edges thereof, held in engagement with said rail base by the' upward .components of opposing torsional forces; I

2. A rail anchor, comprising a cross bar having' two shoulders adapted to engage edges of a rail .base flange :it-opposite sides o" the rail, said bar engaging and exerting upward pressure upon the bottom of the rail base, Harige at opposite sides of the rail in tending to assume a position from which it was sprung and means whereby one end of said bar is given a fixed position in the roadbed as againstthe tendency of the rail to creep.

3. An antici-eeper comprising a transn versely disposed bar having a recess arranged to engage the bottom and oppositev edges of the hase flange of a rail and armsat opposite sides oi said bar adapted to engage the upper surface oi' the rail base at opposite sides of the rail and means engaging a tie for holding one end, otsaid bai' in spaced relation to said tie.
